Support for *.mni files (Mathcad Native Interface file)

HI, I have successfully installed the MathCAD Prime 30-day trial. However, I am unable to open a pre-existing *.mni file (Mathcad Native Interface file).
Does Mathcad Express support them? Is there any way to convert them to a file format recognizable by MathCAD Prime?

Thanks! Eddy

With this background information, and (over the past 30+ years of using Mathcad) never having heard of a 'Mathcad Native Interface' file, my guess is that the company has a Mathcad worksheet file of their own, proprietary, design that contains a function that writes such files. Or else they built it as an add-on function to Mathcad in a .DLL file. In any case, its not available to every Mathcad user, and certainly not to Prime Express users.

The best option would be to ask the company how they create the file, and if they (also) have a function to read the file back in Mathcad.

 

Success!

I've never heard of .MNI files, certainly not within the scope of Mathcad, nor Prime.

Found this onj the internet: http://dotwhat.net/file/extension/mni/3964

Can you attach one such file?

 

Success!
